Ethyl Corporation v. Environmental Protection Agency
United States Court of Appeals for the District of Columbia Circuit
541 F.2d 1 (1976)
The Clean Air Act Amendments of 1970, 42 U.S.C. § 7401, gave the Environmental Protection Agency (EPA) (defendant) authority to protect public health by regulating fuel additives that produced dangerous emissions. The EPA sought to address health concerns relating to lead emissions from leaded fuel. Pursuant to the requirements for informal rulemaking under the Administrative Procedure Act (APA), 5 U.S.C. § 553, the EPA gave notice of its intent to propose rules relating to lead fuel additives, then promulgated proposed regulations for public comment. In 1973, the EPA published final regulations for lead emissions, together with data and research in support of the regulations. The APA provides standards for judicial review of a government agency’s actions in § 706(2)(A), permitting a reviewing court to set aside agency actions, findings, or conclusions if found to be arbitrary or capricious. The Ethyl Corp. (Ethyl) and other lead-additive producers (plaintiffs) appealed the EPA’s emissions regulations to the United States Court of Appeals for the District Columbia Circuit, arguing, among other things, that the EPA’s emissions regulations were arbitrary and capricious. The court found in favor of Ethyl and set aside the regulations. The EPA petitioned for, and was granted, a rehearing en banc by the court, vacating the prior judgment.
